Repeats

Having trouble getting repeats working with your xform? Here are some tips:

Full xform example can be found at bottom of page.

This example demonstrates the use of repeats to add multiple (children in this case) to a form.

Things to note:

	<instance>
		<demog xmlns="">
			<lname>Sims</lname>
			<fname />
			<dob />
			<sex />
			<preg />
			<children>
			  <child jr:template="">			  
			    <name />
			    <fav-color jr:template="">red</fav-color>
			    <age />

In the model instance, both the <child> and <fav-color> elements have a [jr:template=""] attribute. This is essential when you are using repeats to create new nodesets (as in this example). The template attribute basically tells the JavaRosa engine that it should follow that nodesets example when it wants to store the data about a new nodeset that has been generated by answering the questions in the repeat.

...
<group appearance="full">
<label>Child</label>
<repeat nodeset="/demog/children/child">
...

The group tag is useful when for keeping repeat blocks well organized and providing them with a label.
